Highland Axial piston pumps application:
Highland Axial piston pumps are widely used in high pressure, big flow, power systems and the flow needs to adjust the situation, such as machine tools, metallurgy, forging, mining and lifting hydraulic transmission system.
Hydraulic oil notice of Highland axial piston pumps:
The service life of Highland axial piston pump is related to the usual maintenance, the quantity and quality of the hydraulic oil, and the cleanliness of the oil. It is also an effective way to prolong the life of the piston pump to avoid the wear and tear of the friction pair of the piston pump caused by the particles in the oil. The higher the cleanliness of the hydraulic oil, the longer the service life of the hydraulic pump.
